An accurate tachometer and pressure test gauges are required. Test Gauge C-3292 has a 100 psi range and is used at the accumulator, governor, and front servo ports. Test Gauge C-3293-SP has a 300 psi range and is used at the rear servo and overdrive ports where pressures exceed 100 psi. Pressure Test Port Locations Test ports are located at both sides of the transmission case Line pressure is checked at the accumulator port on the right side of the case.

New TRANSBUDDY shift springs allow the minimum throttle 1-2 and 2-3 shift to be calibrated to the correct mph. Note: Some late 1999 and most 2000 and later models shift on time and do not need new shift springs. Do not install shift springs on 1994-95 47RH unless necessary. Early 47RE models 96-98 governor curves vary from vehicle to vehicle so there is no set rule on minimum throttle up shifts. Question: What should my idle pressure be and at what rpm should my trans shift at wide open throttle?
